In this study, we obtained information from twenty-one measurement points on the stress magnitudes and orientations of a gold mine in the Ludong area. We used the overcoring technique with an improved hollow inclusion strain gauge and then analyzed the distribu-tion characteristics of the in situ stress field. The results indicate that the stress field is characterized byσH >σh >σv andσH >σv >σh (whereσH,σh, andσv are the maximum horizontal, minimum horizontal, and vertical principal stresses, respectively). The regional stress field is dominated by horizontal principal stress. TheσH,σh, andσv values show a gradual increasing trend with depth. TheσH is predominantly oriented in the NWW-SEE or near-EW direction. We also confirmed the correspondence between the measured stress field and the regional geological structure. In addition, based on the measured stress data, we discuss the implications of the in situ stress with respect to fault activ-ity in the mine area.
